abi_version/sstate: Bump HASH_VERSION and SSTATE_VERSION
At this point the hash equivalence and sstate is 'junk' on the autobuilder
unforuntately due to the volume of fixes and also the volume of slighly
not quite right patches tested during the development of the fixes.
In order to try and help any remaining sanity I might have, bump the
version numbers to start with a clean slate so we're working from a known
good baseline rather than risk chasing phantom issues. For those
upgrading, there wouldn't be much reuse anyway after the changes.
